The package contains two binaries, fm and fmscan. To pick up all stations even with very weak reception, I issued,

−

$ fmscan -d /dev/radio2 fmscan -d /dev/radio3 -t 18 -i 0.1

+

Scanning range: 87.9 - 107.9 MHz (0.2 MHz increments)...

Nice and clean. I added an antenna, but still got weak reception. This is very useful for testing the radio and finding the stations; does it support directing the sound to a file? I try various combinations and end up with this to get 100% volume:

−

+

−

$ fm -d /dev/radio3 89.9 65535

−

Radio tuned to 89.88 MHz at 100.00% volume

Weird. I don't see a way to record; do I need to use sox? I don't know if I'm getting any sound, as I don't have speakers on this box.

The radio package has a single binary, radio. The man page says it looks for the kradio configuration file ~/.kde/share/config/kradiorc. Failing that, radio tries ~/.radio. I issue,

radio -c /dev/radio3

and get a blue and red curses screen, very cool. Arrow keys increase and decrease frequency in 0.05 intervals. I'm clearly not picking up any signal to speak of. I figure I have a lower-level issue with the tuner.

Radio Listening Software:

There are a number of Radio devices, in particular those TV tuner devices which also contain a radio receiver/tuner, for which V4L directly supports. The following list of software applications allow one to control a radio tuner.

Radio Applications

Gnomeradio and kradio, the most fully featured applications, are not yet available in all distributions and need to be compiled first. Some of the older applications are mature and readily available, but no longer actively developed.

Also See

dvbradio (part of the v4 xawtv package) as an example of a specific application for listening to radio streams embedded within dvb transport streams

User experiences

If you're a user, post your installation and user experiences here!

gnomeradio

Clearly a more sophisticated application. There's only a debian package for i386, so I'll need to build from the tarball. Since I'm mainly interested in remote recording, I'll try fmtools and radio first.

gradio

I tried gradio on Debian amd64, as it's available; it's very basic. If you don't have the card on /dev/radio, start with

gradio -d /dev/radio2

No recording capability, stable gui, minimal functionality -- tuner and volume. I had to hand-edit the .gradiorc configuration file to get station presets; I may have missed some way of doing this through the gui.
